OMNIHASH: Tak, asi daj. Koneckoncu experimenty s presazovanim a slechtenim koralu probihaj. Ale taky nikde neni taky psany, ze se to podari. A ze to budem schopny udelat v nejakym vyznamnym meritku. Jakoze samozrejme muzeme se pokusit udelat amazonskej prales na vysocine a nejvetsi bananovy plantaze v Evrope jsou na Islandu. Nicmene ehm me to tak bezproblemovy neprijde.

OMNIHASH: No, tak bys to mohl rict nejakejm oceanologum, protoze teda co jsem pochopil, tak ty tvrdej neco jinyho. Vetsina koralu ma tohle stoleti vymrit. Protoze moc rychly otepleni, snizovani zasaditosti oceanu, znecisteni a dalsi stresy.



Last refuges for the world’s ailing coral reefs could vanish completely if global warming exceeds 1.5C above pre-industrial levels, a study finds.
Across the world, coral reefs and the wildlife that depends on them face a severe threat from marine heatwaves, which have become 34% more likely over the past century.
At present, 84% of coral reefs are located in regions where conditions allow them to withstand the impact of marine heatwaves, the research says.
However, at 1.5C of global warming, this figure is projected to drop to just 0.2%. And at 2C of global warming, the study projects that all last refuges for coral reefs will cease to exist.

OMNIHASH: Mně to moc pozitivní nepřijde. Zádrhel je v tom "když na to přijde". Kdo vykoupí pozemky zabrané místo pralesa? Jak obnovíme prales ve světě +2 nebo +3 C? Zbytky shoří samy od sebe, už ani nebude potřeba kácet. A obnovovat korálový útesy? No to je marnost největší, proč? Ty jsou odepsaný.

Eradicating ‘extreme poverty’ would raise global emissions by less than 1% - Carbon Brief
https://www.carbonbrief.org/eradicating-extreme-poverty-would-raise-global-emissions-by-less-than-1

The study, published in Nature Sustainability, highlights the global inequality in emissions between people in rich and poor countries. For example, it finds that the average carbon footprint of a person living in sub-Saharan Africa is 0.6 tonnes of carbon dioxide (tCO2). Meanwhile, the average US citizen produces 14.5tCO2 per year.

The authors find that the average carbon footprint in the top 1% of emitters was more than 75-times higher than that in the bottom 50%.

Why the concern about #Ukraine? It is a key grain exporter and it's unknown if a conflict with Russia would disrupt shipments, pressuring global food security

#Ukraine was #China's top #corn supplier until last year, when the U.S. took over (Ukraine had a short crop in 2020 and China's corn needs rose drastically). Is China confident Ukr can supply? Can Ukr ship China's purchases? Will U.S. supplies have to sub in? All valid questions.

This is the focus of the U.S. corn market, but beyond that, countries where food security is a top concern - in the Middle East and North Africa - rely heavily on Ukraine's exports. Disruptions in that trade, if severe enough, could have dire consequences for those citizens.

Ukraine crisis sends grain prices soaring, threatens food security - Nikkei Asia

Food prices could soar even higher if conflict were to break out between Russia & Ukraine, top producers of corn & wheat that are a staple to billions around the world, and raise the specter of runaway inflation & political instability in the Middle East.

Prepare for mass migration to cities in climate crisis, UK mayors warn | Climate crisis | The Guardian
https://www.theguardian.com/environment/2022/feb/16/prepare-for-mass-migration-to-cities-in-climate-crisis-uk-mayors-warn

Mass migration to some of the world’s cities due to the climate emergency is already under way and the World Bank has estimated that unless significant action is taken, 216 million people could be on the move by 2050. In 2020, 30 million people were displaced due to the climate crisis, and 70% of people internally displaced due to the climate crisis are living in urban areas. The World Bank predicts that more than 1 billion people are at risk of being driven from their homes for climate-related reasons.
